操作环境:CentOS 7
、Gcc 4.8.5
、Python 3.10.0
系统上已经有 2.x
,3.6
版本的 Python
了,但是还是想装一个 3.10
的。因为刚写的脚本文件是较高版本的,在 3.6
上无法正常运行,Python
语法不是很了解,只能从环境上下手了。
下载源码文件,然后开始执行操作:
./configure --enable-optimizations
make
sudo make install
然后报错如下,下面是两个机器不同的报错:
# 报错一:
gcc -pthread -Xlinker -export-dynamic -o python Programs/python.o libpython3.10.a -lcrypt -lpthread -ldl -lutil -lm -lm
./python -E -S -m sysconfig --generate-posix-vars ;\
if test $? -ne 0 ; then \
echo "generate-posix-vars failed" ; \
rm -f ./pybuilddir.txt ; \
exit 1 ; \
fi

导致原因
在低版本的gcc
版本,使用 gcc
命令并带有 --enable-optimizations
参数时会出现上面问题。在 gcc 8.1.0
此问题已经修复。
解决方法
1、升级gcc
至 8.1.0
,不是很推荐,可能会影响其他软件的编译。
2、./configure
参数中去掉 --enable-optimizations
。然后执行下面的命令:
./configure
make
sudo make install
如果还不行就将解压的 Python
目录删除掉,重新解压,然后重新执行上面的命令。
